Here are the amazing things that have happened since Cecil's death, just one year ago.
Lions are safer.
The death of Cecil shed light on a floundering population of wild lions in Africa. Since the 1940s, lions have lost about 95 percent of their population, and there are only around 20,000 left in the wild.
Petitions calling for better protections for wild lions circulated widely in the wake of Cecil's death. Each year, big game hunters kill around 600 lions. And with the threats to their populations, it's just not sustainable.
In 2015, France and Australia decided to ban the import of all lion heads, paws and skin trophies.
Finally, in December 2015, the U.S. followed suit, increasing protections for certain subspecies of lions across Africa under the Endangered Species Act.
But there's still room for improvement. Many lions, who aren't considered an endangered subspecies, aren't under the protection of the act ... yet.
